Demo scenes for the full-screen image effect mode depends on Standard Assets’ Camera package, so it needs to be imported along the Demos package (double click on it to uncompress).
Just load any included demo scene and click “Play”. In FPS demos you will be able to move around using WASD or cursor keys. Press spacebar to jump, F to change fog style and T to toggle on/off the fog.
The Fog Of War demo scene allows you to “Cut” the fog as you pass through it (press “C” to enable fog cutting mode).
Finally there’s a Fog of War demo scene that uses the fog of war prefab (only works for the top-down perspective).
You can delete the Demo folder entirely or ignore it when importing the asset into your project.
